A groundbreaking paper in which statistical physics models are used in conjunction with laboratory experiments to show how collective marching emerges at critical population densities in locusts, as a result of simple, local interaction rules between insects. Featured in an accompanying Perspective (Science, 2006, 312, 1320-1322).

The most effective piece of field nutritional ecology ever done, providing a new explanation for mass migration in animals. Demonstrates that huge marching bands of crickets in NW USA are on a forced march driven by specific appetites for protein and salt and the associated risk of cannibalism from other crickets. Was featured in a News & Views in Nature (2006, 440, 38) and Research Highlights in Nature (2006, 441, 8).

The desert locust is an amazing animal. It is notorious as a swarming pest with a voracious appetite, but in fact spends most of its life as a shy solitary individual that carefully balances its food intake to match its body's needs.
